Method of control of a variable reef generating artificial waves

ABSTRACT

An open chamber (88) of predetermined size and shape is positioned within a pool floor (86) so as to contain a plurality of a telescopic module (10) which occupy said chamber area. Each of the telescopic module (10) is independently extended and retracted in length by the rotational direction of an electric motor (54) screw (58) concentrically contained within the confines of said telescopic module (10), establishing in selected telescopic modules a specific reef size, shape, and orientation. When a kinetic-energy (110) within the water passes over the predetermined shape, size, and orientation of the reef, a wave (140) is generated having specific features resulting from the properties of the specific reef configuration.

BACKGROUND—FIELD OF THE INVENTION

The present invention relates to artificial water wave generation in natural and man-made bodies of water for surfing.

BACKGROUND—DESCRIPTION OF PRIOR ART

Water waves occur in natural and artificial bathymetry. Wind, water current, and topographical ocean bed and pool floor features, each and in combination thereof can cause the generation of waves. Relying on naturally occurring conditions and limitations in geographic location can greatly diminish availability, predictability, frequency and quality of waves sought in the art and sport of board surfing. When the topography of an ocean bed or pool floor includes the presence of a reef, the kinetic energy of a wave passing over the reef can be greatly affected by the presence of the reef. The magnitude of the affect is dependent upon several factors, such as the depth of the water, slope at the approach to a beach, wave period, wave amplitude and direction of force in the kinetic energy of the wave with respect to the orientation of the reef. In simple terms, when the bottom-most depth of wave energy comes in contact with the incline approach to a beach, or to a much greater affect, the approach to a reef, the bottom-most depth of wave energy (trough) becomes increasingly retarded. The top-most height of the wave energy (crest) continues to advance with respect to the trough at a constant rate. Eventually, gravity overcomes the unsupported wave crest, and the wave breaks and peels. Attempts have been made to wave size, shape and direction of peel to best meet the demands of the surfer. Artificial reefs have been successfully constructed thereby enhancing the waves generated by wind, topographic features and bathymetry. Such reefs are constructed using mathematical and scaled-down engineering models under conditions of several variables. Scale-down working models are utilized in testing reef size and configuration with hopeful results. However, when full-scale inventions modeled from scale-down models are constructed at extensive cost, the performance is less than expected because of fluid dynamic inconsistencies in the physics of bringing models to full-scale size. The term applied to this phenomenon is “natural similitude”. Most man-made reefs and all-natural reefs are static and thereby exist in specific configuration resulting in drastically limited variation in wave generation. Rigid reef inventions that provide for variation in orientation and alignment with respect to a pool bed provide some variation in wave type, however they do not provide more than one direction of peel, they do not provide variation in the rate of peel of waves generated, they do not provide for desirable wave life before decay, nor do they provide for near infinite wave characteristics or group waves.

In other prior art wave forming devices, attempts have been made to enhance wave size, wave shape, wave duration, and wave direction of peel by placing an adjustable weir onto the bed of the body of water, normal to the direction of flow. The specific incline to the weir and decline to the bed is basically a reef. The elevation of the weir with respect to the elevation of the bed is varied by means of hydraulic piston cylinders, pivot points or combination of both.

Other wave generating devices include rigid reef configurations that are suspended above the bed of the body of water at predetermined distances and predetermined angle of inclination with respect to the direction of water flow, thereby attempting to establish adjustment of the reef in juxtaposition to the bed, water flow, and water depth. Cables and or hydraulic pistons are interconnected, anchored onto the bed and onto the distal surface of the reef. Artificial wave devices that utilize a moving snowplow-like device traveling in a closed circular or elliptical circuit have proved successful in wave generation, however the performance is extremely limited and most important, the concept does not provide linear wave travel as found in nature, and most importantly, does not meet the expectations of board surfers.

In other prior art wave forming devices, a wave is actually simulated in the water itself, rather than being defined by a surface over which a thin sheet of water flows. U.S. Pat. No. 6,019,547 of Hill, Feb. 1, 2000, describes a wave forming apparatus which attempts to simulate natural anti-dune formations in order to create waves. A water-shaping airfoil disposed within a flume containing a flow of water, and a wave-forming ramp is positioned downstream of the airfoil structure.

In other prior art arrangements, such as U.S. Pat. No. 6,928,670 B2, of Lochtefeld et al., Aug. 16, 2005, describes a moving reef wave generator that travels along the surface of a body of water, and preferably in the middle thereof, wherein the wave generator can create both primary and secondary wave that travel toward a shore. The primary waves are intended to allow surfing maneuvers to be performed in a relatively deep-water environment. The secondary waves can break, wherein by modifying the shoreline's slope and curvature, and providing undulating peninsulas and cove areas, various multiple wave formations and effects can be created.

In the prior art of McFarland, U.S. Pat. No. 6,932,541 B2, Aug. 23, 2005, a plurality of a semi-rigid reef, referred to a weir, is interconnected in cantilever onto the bed of a pool of water at the upstream leading end having a predetermined abrupt incline and gentle downward slope at the downstream end. A secondary passageway extends through the bed form, with a first end adjacent the trailing end of the bed form, and a second end in the bed form upstream of the first end, thereby creating a pocket between the bed and underside of the hydraulic rams independently control the lift of each cantilevered reef. A grating is provided between adjacent reefs to prevent inadvertent entry between the reefs and water return channels beneath. However, the grating provides the risk of collision with an occupant in the event of a fall in riding a wave. Furthermore, although the invention provides for some variation in wave size, it does not provide for variation in wave peel direction, wave type, wave size, wave orientation, or wave duration. The flow of water current between wave cycles could create serious rip tides between and beneath the suspended reefs.

In the prior art of Hill, U.S. Pat. No. 6,019,547, Feb. 1, 2000 an airfoil chute or pool and an aero-foil structure shapes the flow of water generated by the chute and variable ramp. Although there is some variation in wave shape of the surfable wave, the rigid surface of both airfoil and ramp limits the variation in reef configuration and thusly wave type, size, and peel. Furthermore, the suspended configuration of the airfoil presents a safety hazard, causing an occupant to become lodged between the airfoil and pool bed.

In U.S. Pat. No. 6,928,670 B2, of Lochtefeld et al., Aug. 16, 2005, the moving reef traverses along the length of a pool near the surface of the water, pulled along a track fastened onto a pool bed. This moving device can be inadvertently impacted by the surfer resulting in serious injury. Even though the device moves, the rigid configuration greatly reduces the variation of wave generation types and direction of wave peel. To enhance wave size, the device must move at a greater rate of speed, thereby increasing the risk of bodily injury if impacted by the surfer. The mechanical means of connecting the moving reef device to the track system creates further risk of injury at the juncture of the moving reefs stem and tracking slot located between the track-mounted trolley and interconnecting moving reef. In testing a wave-generating invention at a scaled-down size, the outcome in full-scale engineering can result in failure. A full-scale production reef was constructed having a buoyant, rigid reef subtended by cables subtended from the distal face of the reef and anchored to a reinforced-concrete pool-bed. When tested, the wave energy generated an uplifting force sufficient enough to separate the attachment of the reef from the pool-bed, virtually pulling the anchored cables from the pool bed, causing millions of dollars in damage and severe delays in the project.

In the prior art of Fuller et al., U.S. Pat. No. 5,219,315, Jun. 15, 1993, a simulator for water rides comprises a theater projection and sound that simulates motion for audience within a raft contained within the confines of a pool completely surrounded with walls. Adding to the simulation is a system for providing water spray, and actuators that provide a “rocking motion” to the raft when the actuators are operating. As such, relative to the earth, there is no actual displacement of the raft and the occupants referred to as the “audience” within the raft. The raft does not traverse any distance with respect to the raft's position to the earth . . . the raft merely experiences the “rocking” motion. In Fuller's invention, the actuators are either connected directly to the raft or the actuators are connected to a flexible plate which transmits agitation to the water contained within the pool which in turn, “rocks” the raft. Regardless of either configuration, in order for any rocking motion to be imposed to the raft, the actuators must be in motion since the actuators generate the “rocking” motion. When the embodiment utilizes the flexible plate to agitate the water, flexibility can only occur in one horizontal axis at a time because the plate cannot be stretched or compressed. This physical limitation of the plate limits the “rocking” motion to either side-to-side with respect to the raft, or front-to-back with respect to the raft. When the embodiment utilizes having the actuators connected directly to the raft, the rocking motion of the raft experiences can be more random with respect to side-to-side and/or front-to-back. However, in this particular embodiment whereby the actuators are connected directly to the raft, there is no need for water within the pool, further demonstrating the fact that the invention is merely a simulator, since the raft “rocks” without having the presence of water to both “rock” and support the raft in the stationary, “rocking” position.

In the prior art of Fricano, U.S. Pat. No. 9,175,488 B2, Nov. 3, 2015, an open chamber of predetermined size and shape is positioned within a pool as to contain interconnect clusters of interconnected telescopic modules which occupy the chamber area. Each of the telescopic modules is independently extended and retracted in length vertically by the increase or decrease of the volume of water contained within a bellows. Concentrically fitted within the telescopic module, the proximal end of the bellows is fastened to the proximal end of the telescopic upper body. The distal end of the bellows is fastened to the distal end of the stationary lower body where the bellows is interconnected with a water supply and evacuation tube. The volume of water contained within the bellows established the extension or retraction of the bellows, thereto establishes the extension or retraction of the telescopic upper body with respect to the stationary lower body of the telescopic module. The plurality of selected telescopic modules each extended or retracted to a specific predetermined height above or at the plane of a pool bed establishes a specific reef size, shape, and orientation. As such, the three-dimensional shape of the reef determines the characteristics of the water wave desired. The bellows element of the invention functions efficiently and effectively. An important advantage implementing water in lieu of a hydraulic oil-based fluid through the supply tube and bellows is the elimination of risk of leakage of toxic fluid from the supply tube and bellows seeping into the pool water environment due to seal failure of the bellows and/or supply tube.

SUMMARY OF THE INVENTION

In accordance with the present invention, there is provided a reef that is comprised of a plurality of a telescopic-module that is grouped in a plurality of interconnected clusters thereby establishing contiguous three-dimensional variations for a reef. Each cluster is configured geometrically, comprised with a primary-module which is center-positioned and is interconnected with a surrounding plurality of a secondary-module. The primary-module acting as a hub, extends downwardly and beyond the distal end of the secondary-module thereby supporting the secondary-module. The geometric arrangement is much like pedals of a flower, whereby the secondary-telescopic-module represent the pedals and the primary-telescopic-module represents the hub, with a stem extending downwardly and beyond the distal end of the secondary-telescopic-module. The domain of the variable reef is established so as to provide the desired characteristics of specific waves desired. As a means of establishing the domain of the plurality of the telescopic-module within the confines of a pool floor, a chamber is provided. The chamber, communicating with a pool floor, is configured to a predetermined size, shape, and depth below the elevation of the pool floor, thereby acting as a yoke to restrict lateral movement of the plurality of the telescopic-module clusters when acted upon by a kinetic-energy of water passing above the entire domain of the reef.

The predetermined depth of the chamber dependent upon a predetermined maximum reef height required above the elevation of the communicating pool floor plane so as to achieve specific wave height characteristics. As such, the range of the telescopic-module extension from a full-retracted attitude coplanar with the pool floor to a full-extended attitude dictates the chamber depth beneath the pool floor. Furthermore, a minimal depth of the chamber is defined by a predetermined distance below the distal end of the plurality of the secondary-module so as to permit technicians to traverse between the module clusters for the purpose of construction and maintenance of the reef system. This provision omits “down-time” in the event of repairs to the telescopic-modules.

The domain of the telescopic-module provides for a variety of reef shape, size, and orientation within the confines of the chamber, thereby providing a means of generating a variety of wave shape, size, orientation, direction of peel, and duration of peel. Each of the telescopic-module is controlled independently so as to vary in extension or retraction independently. When completely retracted, the telescopic-module height is aligned within the same plane as the circumventing pool floor thereby establishing a condition as if no reef exists. When a plurality of predetermined telescopic-module is selected and activated to “telescope” or extend upwardly, each at a progressive predetermined height, the telescopic-module group acts in totality to create a unique, predetermined reef shape thereto creating a specific wave generation. In either scenario, the contiguous array of telescopic-modules to each other and to the confines of the chamber thereto communicating to the pool-floor, prevents the possibility of a swimmer or surfer from inadvertently becoming trapped between the adjoining telescopic-modules. Extension and retraction of each telescopic-module is accomplished by means of a direct current electric-motor comprising an extended armature configured as a screw with mating nut, whereby a predetermined polarity and a predetermined dwell-time of electric current supplied from an external source to the direct current electric-motor determines whether the telescopic-module extends or retracts. When electric current of predetermined polarity and dwell-time is applied to the electric-motor, the electric-motor screw rotates in one direction, thereby causing the telescoping-upper-body to elevate to a predetermined height above the plane of the encompassing pool bed. Conversely, when electric current applied to the electric-motor is of a predetermined opposite polarity, the electric-motor screw rotates in the opposite direction, thereby causing the telescoping-upper-body to retract to a predetermined height above or at the plane of the encompassing pool bed. Once the desired attitude of each the telescopic-module is attained as a result of a predetermined dwell-time of electric current, no further displacement of motion of the telescopic-module takes place until the reef profile is necessary to provide a variation in wave performance is desired. As such, the telescopic-module extension or retraction motion does not create the wave energy. The wave energy is created upstream from the reef and the configuration of the reef causes the wave energy to generate specific variations in wave characteristics when the energy passes over the specific reef. These variations in reef shape, size, and orientation provide for creating various wave types, size, direction of peel, duration of peel, single and multiple simultaneous wave generation.

In accordance with the direction of the kinetic-energy introduced to the water within the pool, a diagonal-left reef extends down-stream towards a (optional) beach traversing from right to left, thereby causing the kinetic-energy over-passing the diagonal left reef to generate a wave which will peel or break from right to left along a plateau of said diagonal-left-reef. Conversely, in accordance with the direction of the kinetic-energy introduced to the water within the pool bed, a diagonal-right-reef extends downstream toward a (optional) beach traversing from the left to the right, thereby causing the kinetic energy overpassing the diagonal right reef to generate the wave which will peel from left to right along the plateau of said diagonal-right-reef.

When a reef is configured in a vee-shape with the vertex located at or near the centerline of the pool and upstream, convex to the direction of the kinetic-energy, the wave generated peels from the vertex in both directions along the plateau of the reef. The desired configuration, size, and orientation of any reef type is determined by means of testing at full-scale for the purpose of creating the optimum wave performance. Upon testing for each specific wave type, size, and orientation, the predetermined dwell time and polarity of electric current provided to each individual telescopic-module is programed into a computerized system for subsequent settings desired in reef shape, size, and orientation. This full-scale testing and evaluation is executed in a condition termed “natural similitude”. As such, the programmed settings providing specific predetermined reef configurations can be adjusted for subsequent testing of wave performance characteristics for the purpose of enhancing the wave characteristics desired. Furthermore, the domain of the reef and thusly the size and shape of the chamber is established with a predetermined size and shape, omitting areas within the confines of the pool floor where the variable reef would prove ineffective. This measure of establishing the domain size and shape provides considerable economies of scale in cost savings.

The cylindrical longitudinal shape of each set of three of the tangential adjoining telescopic-module provides a vertical equilateral concave triangular void. The void provides for circulation of water contained within the pool to pass downwardly through each of the void into the chamber and circulate from the chamber to a pumping filtration and purification system (not shown) located outside the confines of the pool, thereto returning filtered and purified water to the pool. Furthermore, the void provides for light to pass upwardly from an electric light source within the confines of the chamber to the pool area defined by the domain of the reef. This light source provides for aesthetic visual effect after dark and provides for illumination in the event maintenance is required from within the confines of the chamber.

DETAILED DESCRIPTION

FIG. 1A is a side view of a telescopic-module 10 partially extended. The telescopic-module 10 is comprised of a telescoping-upper-body 12 and a stationary-lower-body 14. Extension and retraction of the telescoping-upper-body 12 varies in position relative to a stationary-lower-body 14 from a full-retracted-length 38 (first shown in FIG. 2B) to a full-extended-length 40 (first shown in FIG. 2A). The extension and retraction of the telescoping-upper-body 12 is accomplished by a direct current electric-motor 54 concentrically attached within the telescopic-module 10. Powered by an outside electrical source (not shown), electric current is directed to the electric-motor 54 by means of a electrical-conductor 56 comprised of two wires for the purpose of conducting reciprocal polarity. Along a centerline 34, the proximal end of the telescoping-upper-body 12 is fitted with a hemispherical dome 16 made of an elastomeric polymer material such as silicone so as to compress if inadvertently impacted by a swimmer or surfer. Memory of the dome 16 material causes the dome 16 to recover to a pre-impact shape subsequent to impact. Longitudinally inserted within the telescoping-upper-body 12 is the stationary-lower-body 14 of predetermined outside diameter so as to provide insertion of a plurality of a screed 20 positioned equidistantly and longitudinally between the telescoping-upper-body 12 and the stationary-lower-body 14. The screed 20 is comprised of a glide-channel 22 which is longitudinally attached onto the outer face of the stationary-lower-body 14. Mating with the glide-channel 22 is a glide-rail 24 (first shown in FIG. 2A) which is attached onto the inner face of the telescoping-upper-body 12 thereby providing slide-ability of the telescoping-upper-body 12 with the stationary-lower-body 14 so as to avoid concentric misalignment or rotation of the telescoping-upper-body 12 with respect to the stationary-lower-body 14. The stationary-lower-body 14 is circumferentially fitted with a collar 18 of outside diameter equal to the outside diameter of the telescoping-upper-body 12. The collar 18 provides for proper parallel alignment when interconnected with one or more of the telescopic-module 10.

FIG. 1B is a cross sectional view showing a plurality of the screed 20 equidistantly positioned circumferentially between the stationary-lower-body 14 and telescoping-upper-body 12. Communicating with the glide-channel 22 is the glide-rail 24 which is attached onto the inner face of the telescoping-upper-body 12 for providing slidability and engagement between the telescoping-upper-body 12 and the stationary-lower-body 14. The screed 20 also prevents inadvertent rotation of the telescoping-upper-body 12 with respect to the stationary-lower-body 14 caused by torque generated during extension and retraction of the telescoping-upper-body 12. The extension and retraction of the telescoping-upper-body 12 is accomplished by the rotation of a external screw 58 extension of the armature of the electric-motor 54. The imposing torque of the screw 58 of the electric-motor 54 is transmitted to the upper-telescoping-body 12 by a flanged-nut 52 (first shown in FIG. 2A) fitted onto the distal end of a distal-flanged-collar 50 (first shown in FIG. 2A) which is attached onto the distal end of a nut-retaining-cylinder 46 (first shown in FIG. 2A) which is thereto attached onto the proximal end of a proximal-retainer 42 (first shown in FIG. 2A) communicating with the upper-telescoping-body 12. A circumferential-gap 26 is established to provide placement of the screed 20 between the stationary-lower-body 14 and telescoping-upper-body 12. The gap 26 provides for effluent flow of water from within the cavity of the dome 16 and influent flow of water into the cavity within the dome 16, allowing the dome 16 to collapse and recover in the event the dome 16 is inadvertently impacted by a surfer or swimmer, thereby avoiding bodily harm.

FIG. 1C is a close-up view showing the cross-sectional profile of the screed 20 comprised of the glide-channel 22, the glide-rail 24, and the circumferential-gap 26 for clarity.

FIG. 2A is a longitudinal cross-sectional view of the telescopic-module 10 showing the full-extended-length 40 and a displacement 36. A proximal-flanged-collar 48 is permanently bonded into the proximal end of a nut-retaining-cylinder 46. A distal-flanged-collar 50 is permanently bonded onto the distal end of the nut-retaining-cylinder 46. The proximal-flanged-collar 48 installed onto the proximal end of the nut-retaining-cylinder 46 is then attached onto the underside face of a proximal-retainer 42 by means of a plurality of a first-fastener 64. The flanged-nut 52 is attached onto the distal-flanged-collar 50 positioned at the distal end of the nut-retaining-cylinder 46 by means of a second plurality of the first-fastener 64. The proximal-retainer 42 comprised of the assembly of the proximal-flanged-collar 48, the nut-retaining-cylinder 46, the distal-flanged-collar 50, and the flanged-nut 52 is then insertibly fitted into the proximal end of the telescoping-upper body 12 and is attached by means of a second-fastener 66. The dome 16 of the telescopic-module 10 is elastically captured onto the proximal-retainer 42. A breather-port 30 is positioned through the horizontal surface of the proximal-retainer 42 to provide for the effluence and subsequent influence of water flow when the elastic dome 16 collapses then recovers from an inadvertent impact by a swimmer or surfer. The circumferential-gap 26 provides for influent and effluent water displacement corresponding with the water displacement through the breather-port 30. The armature shaft of the electric-motor 54 extends externally through the proximal end of the electric-motor 54 housing which is threaded so as to perform as the screw 58. The screw 58 portion of the electric-motor 54 is passively positioned upwardly from the under-side of a distal-retainer 44 through a concentric opening of the distal-retainer 44 subsequent to installation of a gasket 60 sandwiched between the electric-motor 54 proximal end and the distal-retainer 44 which prevents water from inadvertently infiltrating into the electric-motor 54 housing. A threaded washer 62 is placed onto the upper face of the distal-retainer 44 capturing the distal-retainer 44, the gasket 60, and electric-motor 54 when a plurality of a third-fastener 68 passing upwardly through the electric-motor 54, the gasket 60, and the distal-retainer 44 is threadably attached to the washer 62. This configuration establishes a water-tight seal between the electric-motor 54, the screw 58 and the distal-retainer 44. The distal-retainer 44 is then insertably fitted into the distal end of the stationary-lower-body 14 and attached onto the stationary-lower-body 14 by means of a fourth-fastener 70. The telescoping-upper-body 12 is concentrically positioned onto the proximal end of the stationary-lower-body 14 so as to provide engagement of the screed 20 glide-channel 22 with the screed 20 glide-rail 24. The telescoping-upper-body 12 is further engaged with the lower-stationary-body 14 until the proximal free end of the screw 58 of the electric-motor 54 makes contact with the flanged-nut 52 during the installation process. Full engagement of the telescoping-upper-body 12 and stationary-lower-body 14 is accomplished when the screw 58 of the electric-motor 54 and the flanged-nut 52 become threadably engaged. A predetermined polarity and predetermined dwell-time of low voltage and low amperage direct electric current transmitted by means of the electric-conductor 56 to the electric-motor 54 establishes full-engagement of the screw 58 with the flanged-nut 52, thereby establishing complete assembly of the telescoping-upper-body 12 with the stationary-lower-body 14. An important advantage utilizing direct current in lieu of high voltage and high amperage alternating current is that low voltage and low amperage direct current prevent the danger of electric shock in the event of an electrical short due to electrical contact with water. Another benefit to utilizing a direct current electric-motor 54 is to provide control of electric polarity. When the electric-motor 54 is powered in positive to negative polarity direction, the electric-motor 54 will rotate in one direction. When the electric-motor 54 is powered in negative to positive polarity direction, the electric-motor 54 will rotate in the opposite direction. Hence, control of electrical polarity powered to the electric-motor 54 determines the direction of rotation of the screw 58, thereby determining whether the telescoping-upper-body 12 extends or retracts accordingly. Furthermore, the pre-determined dwell-time of electric current determines the predetermined displacement 36 of the telescoping-upper-body 12 with respect to the stationary-lower-body 14.

FIG. 2B is a longitudinal cross-sectional view of the telescopic-module 10 in the full-retracted-length 38 attitude.

FIG. 3 is a longitudinal cross section view of a cluster 98 (shown as a schematic top view in FIG. 5) of the telescopic-module 10 showing various lengths of extension ranging from a full-retracted-length 38 attitude to the full-extended-length 40 attitude. The cluster 98 is comprised of a primary-module 74 and a plurality of a secondary-module 76. Acting as a hub, the primary-module 74 is centered and surrounded geometrically by the plurality of the secondary-module 76. All of the telescopic-module 10 are interconnected with a plurality of a fifth-fastener 78 at a interface 94 through the interconnect-bore 32. The fifth-fastener 78 is introduced through the assembly of interconnect-bore 32, the distal-retainer 44, the stationary-lower-body 14, and the collar 18, thereby interconnecting adjoining telescopic-module 10 in establishing the cluster 98. The adjoining plurality of the cluster 98 of the telescopic-module 10 create a building-block for a contiguous variable reef-domain (first shown in FIG. 8) which is defined within a chamber-perimeter 106. The cluster 98 provides for establishing a means for having the cluster 98 pre-fabricated to enable the reef-domain defined within the chamber-perimeter 106 to be assembled with less effort and improved efficiency. The collar 18 of the stationary-lower-body 14 of the primary-module 74 extends downwardly a substantial predetermined distance beyond the stationary-lower-body 14 of the plurality of the surrounding secondary-module 76 of the cluster 98 and communicates with a base 72 which in turn is anchored onto a chamber-floor 92 of a chamber 88 by means of a plurality of a sixth-fastener 80. The primary-module 74 serves as a center column to support the weight and maintain position of each of the cluster 98 to resist hydrodynamic forces generated by a kinetic-energy 110 in a wave 140 (shown in FIG. 10) generation process. Furthermore, this configuration provides a technician with adequate space between the adjoining cluster 98 during installation and maintenance procedures from within the chamber 88. The configuration shows an independent predetermined extension of each of the telescopic-module 10 for the purpose of establishing a predetermined general-contour 84. When all in the plurality of the cluster 98 are interconnected, the contiguous variable reef is established. When all of the telescopic-module 10 are postured in the full-retracted-length 38 attitude within the same plane as a pool-floor 86, essentially there is no reef. When a predetermined selection of the telescopic-module 10 are extended or retracted to desired independent lengths, a specific shape, size, and oriented reef is established, thereto generating a conforming specific wave 140 (shown in FIG. 10) when the water is acted upon by the kinetic-energy 110.

FIG. 4 is a lateral cross-section view of the cluster 98 of the telescopic-module 10 showing the primary-module 74, a plurality of the secondary-module 76, a plurality of the fourth-fastener 70, and a plurality of the fifth-fastener 78. The equidistant relative position between each of the fourth-fastener 70 is shown as a first-angle 102 having three of the fourth-fastener 70 axially positioned at 120 degrees. The equidistant relative position between the sequential fourth-fastener 70 and the fifth-fastener 78 is shown as a second-angle 104 axially positioned at 30 degrees. This arrangement of positioning the fourth-fastener 70, and the fifth-fastener 78 provides a systematic means of pre-assembly of the telescopic-module 10, the assembly of the cluster 98, and the interconnection of adjoining plurality of the cluster 98. A cluster-perimeter 100 defines the general hexagonal geometric shape generated by a plurality of the encompassing secondary-module 76. A tier of one encompassing row of the telescopic-module 10 is shown. However, the number of concentric tiers can vary from a single encompassment to two or more, thereto increasing the number of the secondary-module 76 required from six to eighteen respectively, and so forth. Each of the tangential adjoining telescopic-module 10 establish the interface 94. The area between each of the three-adjoining telescopic-module 10 create an equilateral triangular concave void 96. The void 96 provides a conduit for water circulation from a pool 150 (shown in FIG. 10) into the chamber 88. Water is pumped from the chamber 88 to a purification and filtration system (not shown) outside the confines of the pool 150 and is thereto circulated back to the pool 150. Another purpose of the void 96 is to illuminate the water above the area of the reef from within the confines of the chamber 88 by providing electric lighting fixtures at predetermined locations attached onto the chamber-floor 92, directing light upwardly through the void 96 thereby creating a visual enhancement after dark. The illumination will also provide light necessary for repairs to the telescopic-module 10 from within the chamber 88.

FIG. 5 is a top schematic view of a plurality of the cluster 98 of the telescopic-module 10, and the cluster-perimeter 100 of the plurality of the cluster 98 interconnected. The interface 94 is the location for interconnection of each of the telescopic-module 10, and the adjoining cluster 98 by means of a plurality of the fifth-fastener 78 (first shown in FIG. 3). Juxtaposition of each of three of the tangentially adjoining telescopic-module 10 creates the void 96 which provides for water circulation from the pool 150 communicating with the chamber 88, and pool illumination above the reef-domain which is defined within the chamber-perimeter 106.

The geometric configuration of the chamber 88, as defined by the chamber-perimeter 106, in lieu of a simple rectilinear perimeter, greatly reduces the number of the telescopic-module 10 by omission of areas where the reef is not required, thereto providing a cost saving. The chamber 88 is comprised of a chamber-centerline 108 parallel to the kinetic-energy 110 direction for providing a reciprocal of any configuration.

The vee-reef 112 generates the wave 140 with the peel 120 beginning at the chamber-centerline 108 and moving outwardly, and equidistantly in both directions as shown. The telescopic-module 10 located in the area established between the chamber-perimeter 106 and surrounding the vee-reef 112 is a dormant reef 118 which remain in the full-retracted-length 38 attitude. FIG. 6B is oriented for clarity so as to provide interpretation of the reader of the invention as being the surfer moving in the direction of the kinetic-energy 110. Chamber 88 defines the reef-domain which is defined within the chamber-perimeter 106. The shape of the vee-reef 112 is not necessarily limited to be confined within the outline of FIG. 6B as this outline merely provides for a general configuration of the vee-reef 112, and the wave 140 generation option.

FIG. 6C is a plan view of the chamber 88 showing within outline a predetermined diagonal-left-reef 114 for generating the wave 140 (shown in FIG. 10) having the peel 120 direction of the breaking wave 140, and the kinetic-energy 110 direction. The diagonal-left-reef 114 generates the wave 140 with the peel 120 beginning at the right showing the direction of the peel 120. Chamber 88 defines the reef-domain which is defined within the chamber-perimeter 106. The telescopic-module 10 located in the area established between the chamber-perimeter 106 and surrounding the diagonal-left-reef 114 is the dormant reef 118 which remain in the full-retracted-length 38 attitude. FIG. 6C is oriented for clarity so as to provide interpretation of the reader of the invention as being the surfer moving in the direction of the kinetic-energy 110. The shape of the diagonal-left-reef 114 is not necessarily limited to be confined within the outline of FIG. 6C as this outline merely provides for a general configuration of the diagonal-left-reef 114, and the wave 140 generation option.

FIG. 6D is a plan view of the chamber 88 showing within outline a specific diagonal-right-reef 116 for generating the wave 140 (shown in FIG. 10) having the peel 120 direction of the breaking wave 140, and the kinetic-energy 110 direction. The diagonal-right-reef 116 generates the wave 140 with the peel 120 beginning at the left showing the direction of the peel 120. The chamber 88 defines the reef-domain which is defined within the chamber-perimeter 106. The telescopic-module 10 located in the area established between the chamber-perimeter 106 surrounding the diagonal-right-reef 116 is the dormant reef 118 which remain in the full-retracted-length 38 attitude. FIG. 6D is oriented for clarity so as to provide interpretation of the reader of the invention as being the surfer moving in the direction of the kinetic-energy 110. The shape of the diagonal-right-reef 116 is not necessarily limited to be confined within the outline of FIG. 6D as this outline merely provides for a general configuration of the diagonal-right-reef 116, and the wave 140 generation option.

FIG. 7 is a perspective view of the cluster 98 of the telescopic-module 10 showing the primary-module 74, and a plurality of the secondary-module 76. The collar 18 of the primary-module 74 extends downwardly communicating with the base 72 thereto communicating with the chamber-floor 92 of the chamber 88. The base 72 is anchored onto the chamber-floor 92 by means of a plurality of a sixth-fastener 80, thereby preventing uplifting dynamic force caused by the wave 140 (shown in FIG. 10) generation across, and above the reef-domain which is defined within the chamber-perimeter 106 (shown in FIG. 8). A access-opening 82 within the collar 18 of the primary-module 74 is provided in proximity to and below the distal-retainer 44 for the purpose of assembly, and passage of the electric-motor 54, and the electric-conductor 56. Each of the telescopic-module 10 is operated independently for establishing variation in extension of the telescopic-module 10 thereto establishing variation in reef size, shape, and orientation.

FIG. 8 is a plan view of the reef-domain which is defined within the chamber-perimeter 106 within the confines of the chamber 88 showing to full capacity, the total population of the telescopic-module 10 establishing the domain within the chamber-perimeter 106. The diagonal-right-reef 116 is comprised of a series of three distinct planes comprising a proximal-slope 122, a plateau 124, and a distal-slope 126, given in the respective sequence to the kinetic-energy 110 direction. The direction of the peel 120 is shown to begin at the left of the diagonal-right-reef 116 as the kinetic-energy 110 advances toward a beach (not shown). One of the cluster 98 positioned within the dormant-reef 118 field is defined independently for clarity. FIG. 8 is oriented for clarity so as to provide interpretation of the reader of the invention as being the surfer moving in the direction of the kinetic-energy 110. The shape of the diagonal-right-reef 116 is not necessarily limited to be confined within the outline of the diagonal-right-reef 116, as this outline merely provides for a general configuration of the reef, and the wave 140 generation option.

FIG. 9 is a perspective view of the reef-domain which is defined within the chamber-perimeter 106 within the confines of the chamber 88 showing the predetermined diagonal-right-reef 116, the peel 120 direction, and the kinetic-energy 110 direction. A length 130 of the diagonal-right-reef 116 is shown corresponding to a width 132 of the diagonal-right-reef 116. A height 134 of the diagonal-right-reef 116 represents the elevation of the plateau 124 with respect to the pool-floor 86 (shown in FIG. 10). The dormant-reef 118 is shown outside the delineation of the diagonal-right-reef 116 which represents the plurality of the telescopic-module 10 which remain coplanar to the pool-floor 86. As the kinetic-energy 110 passes in the general direction as shown, the kinetic-energy 110 is confined by approach to a toe 128 along the length 130 of the proximal-slope 122, and continues to be further confined along the proximal-slope 122 to the plateau 124, causing the wave 140 (shown in FIG. 10) to break and create the peel 120 (shown in FIG. 10) before passing beyond the distal-slope 126. Reef size, orientation, or configuration can be modified or changed from the diagonal-right-reef 116, the diagonal-left-reef 116, the vee-reef 112, or any combination or plurality thereof simply by changing the polarity and dwell-time applied to the electric-motor 54, thereby changing the direction of rotation of the electric-motor 54 and thusly the direction of rotation of the screw 58 of each of the independently controlled telescopic-module 10.

FIG. 10 is a cross sectional view of the chamber 88 within the confines of the pool-floor 86. The chamber 88 is comprised of a chamber-wall 90 thereto communicating with the chamber-floor 92 of the chamber 88 for establishing the chamber-perimeter 106. Furthermore, communicating with the chamber-wall 90 of the chamber 88 is a raceway 138, thereto communicating with a electric power control station (not shown) located outside the confines of the pool 150. The electrical-conductor 56 which supplies current to the electrical-motor 54 is extended from each of the telescopic-module 10 to the electric power control station (not shown) beyond the confines of the chamber 88 through the raceway 138. The raceway 138 also provides for chamber 88 access during construction, and maintenance of the plurality of the telescopic-module 10. The polarity of the electrical current supplied to each of the electric-motor 54 of the telescopic-module 10 is controlled independently by means of a computerized switching system (not shown), causing the electric-motor 54 to rotate either clockwise or counter-clockwise, altering the juxtaposition of the screw 58 of electric-motor 54 with the flanged-nut 52, thereto causing the telescopic-module 10 to extend or retract respectively. The totality of telescopic-module 10 within the confines of the chamber 88 are programmed to either remain in part with a predetermined dormant-reef 118, or are programmed to establish the predetermined size, and shape of a specific reef, or plurality of reefs. The basic reef configurations are shown in FIG. 6B, FIG. 6C, FIG. 6D. Referring again to FIG. 10, the predetermined profile of the diagonal-right-reef 116 is shown communicating with the dormant-reef 118. The elevation, and horizontal plane of a static-water-line 146 is disrupted by the wave 140 kinetic-energy 110, thereby creating a dynamic-water-line 148. As the kinetic-energy 110 within the water approaches the toe 128 of the diagonal-right-reef 116, the kinetic-energy 110 nearest the surface of the proximal-slope 122 becomes increasingly retarded relative to the energy velocity at the water's surface to a specific depth (which is dependent upon several factors). This “dragging” effect increases until the kinetic-energy 110 of the wave 140 reaches the plateau 124 causing the wave 140 to generate a crest 142. The crest 142 advances beyond the relative position of the wave 140 as the kinetic-energy 110 becomes increasingly retarded when in contact with the proximal-slope 122, creating a face 144 of the wave 140. Overcome by gravity, the mass of the water above the static-water-line 146 at the crest 142 and the wave 140 begins to collapse and create the peel 120 in a direction influenced by the advancing direction of the diagonal-right-reef 116 towards a (optional) beach (not shown). Hence, the peel 120 direction is to the right, thereto providing a “barrel” or riding surface for the surfer as the wave 140 continues to generate the peel 120 and finally decay toward the beach (not shown). Since other modifications and changes varied to fit particular operating requirements and environments will be apparent to those skilled in the art, the invention is not considered limited to the example chosen for purposes of disclosure, covers all changes and modifications which do not constitute departures from the true spirit and scope of this invention.
